ROTARY-CYLINDER INT To all whom, it may concern Be it known that I JORDAN Annals a sub ject of the King of (heat Britain and Ireland, and re. ideut of London, England, have invented. certain new and useful In'nn'ove ments in and Relating .to Rotary-Cylinder Internal-Combustion lilngines, of which the following-is a specification This invention relat is to improvements in four-cycleinternal combustion engines of the radial rotating cylinder type.

To this end the invention has in view certain novel features of ccnistruction in enof this character wherein the explosive mixture is drawn into the crank chamber through a hollow crank shaft, and from there conveyed. through ports in the crank chamber wall to an annular chamber outside of the crank case. l rom this chamber the mixture is then passed by means of suitable.

pipes or the like :to the cylinder through the inlet Valve in. each of the cylinder heads, by means of specially d.e..',g'ncd controlling devices.

Accorli tlingly, the invention also has in. view a novel valve arrangement, and novel valve act ating devices which greatly improve the structural features of the engine, and enable the diameter of the same to be reduced.

l h I V n l A iurther oluect is to provide a novel,

simple and practical. arrangement of instrumentalities, whereliiy the ellicieucy of the engine is n'laterially i.nere:.1.sed, and all of the iiarts are cayurble of cooperation in a posi-- ti d reliable nniuner.

Fig. lis a part 'vertical section of a modified construction; and,

Fl. 5 a plan view also illustrative of i'nodi cations hereinafter referred to.

u: is the reference letter for all the cylinders, b for all the pistons, c the col'niectni rods, d is the crank pin, and. c is the cral'llc shaft, one end of which. is hollow having the duct 6, for the conveyance of'the mixnor. The mixture is conveyed from the crank chamber 7' through ports in the wall thereof indicated by the arrow to the annular chamber 9 thence by the pipes h to the inlet valve box z by the inlet valve j to the combustion chainljier. The recess i formed in. the valve box 5 within which the The valve stem or spindle has two guides, that formed in thecylind 1' head. it, and that in the recessed will of the valve box, the springbeing fitted between them.

The inlet valve box secured by the lults i to the top cooling web plate, and. by the screw to the central. cooling web of the cover The cylinder cover it fits within the cylin' der and is secured on the inner side by a flange It" formed integrally with and his" a the cylinder, and on the outer 5.. le

annular nut lfiywhose thread fits th The stem of th. exhaust valve 5 a guide Z formed integrally with the cover plate 71:. lllhis guide d by the dininetral 1' Z (Fig.5. 3) dividing the outlet for the on taunt into two ports Z Z 'll'is valve it o .(l. by the lever Z" .u'iounted on thesanie :tulcruin pinv m as the aid lever e l fits within a longitudinal slot irn: (l in the lever 3 and. both lev' being i ounted on. the same fulcrum. pin m, the lever 5 haviiw" two hearings thereon, they or te in o phrne. 1 this manner the two valves diannitrajlily arranged are operated. by the two push rods and j in. the

sauna plane, and the push rods may be op erated asshown by the cams l and j" on the '1 rue sleeve a, the axis of which is in lane. The said cams, sleeve and gear \vh ale are integrally :torrned, and are mounted on. the tired pin 0 secured in the crank chalnhcr l 'The push rods Z and j are each provided at their uppc ends With. a eap hai ing a cylinder or stationary.

' pins thus pass through the lever.

At the other or inner ends of each pus rod a ball is'fitted to take the friction of the cam.

The fulcrum pin m is mounted in an eye bolt or carrier m secured by nuts in the upper annular cooling webs of the cylinder.

. The conical deflector or shield p is fitted to the guide Z of the exhaust valve Z in order to protect the spring from the heat of the hot exhaust gases passing outwardly through the ports Z Z in the cover k.

Referring to Fig. 2, g'is the distributing plate controlling of the engine. The plate 9 1s annular and is formed of suitable non-conducting material. It is securedto the outer casing r'of the bearing. A conducting block of metal 8 is inserted in afrecess formed in the distributing plate to receive it, and the eye screw 8' is screwed through the metal block. The wire for connection to the spark plug it is secured in the eye of the screw.

The cylinders a, a are formed with a thread on their inner ends and are screwed into corresponding threads in the crankchamber and then locked by the annular nutsa, u.

Referring now to the modification shown in Figs. 4 and 5, j is the exhaust valve box which is 'provided with the depression or recess 7' throu h which extends the exhaust valve spindle this. recess or depression 7'" serving also for the accommodatlon of the rocking levers Z, the exhaust box 7' being connected suitably to any convenient form of silencer, either rotating with the The two valves, the inlet valve j and the exhaust valve Z are closed and kept closed by means of'the leaf orblade spring jfluntil such time as they are opened by their rocking levers. This spring one or several plates and to the central web 71* of the cylinder head, or to a. bracket thereon, or'it may be pivotally 17;" may consist of mounted thereto so that said spring may have a certain degree of rocking movement upon its pivot, in such manner that the arms of said spring are of equal length. Each end of this centrally mounted spring j is forked or slotted at its'end 2 to embrace the valve spindles j, Z, and said forked ends 2 press against pins 3 in the valve spindles j, Z, or against a nut on said spindles pro vided with a rounded projecting ortlon to contact with the aforesaid fork ends of the spring.

4, 4 are balls adapted to contact with the and timing the ignition top ends of the valve spindles j, Z, said I balls being held within or partly embraced by recesses 5 at the ends 6 of the rocking levers j, Z, said recesses being slotted or longer in the longitudinal direction of the levers than in the lateral to allow of the slight rolling movement of the balls 4 owing to the rocking of the levers j, Z.

To prevent any side rock, 'the longer or inlet valve levergslides within slotted guides Z which are preferably formed in the central web i, but said guides may be otherwise arranged.

Having now described my invention, what I claim as new and desire to secureby Letters Patent of the United States is 1. An engine of the class described including in combination, a cylinder having inlet and exhaust ports in the head thereof, valves for said inlet and exhaust ports, an upstanding lever guide member carried by the cylinder head and located between said ports, and separate inlet and exhaust valve operating levers nested one within the other and having a common fulcrum point, said inlet valve lever working in said guide member.

2. An engine of the class described including in combination, a cylinder havinginlet and exhaust ports in the head thereof, a casing secured to the cvlinder head and communicating with said inlet port, said casing having a lever clearance recess, springseated inlet and exhaust valves for said ports, an upstanding lever guide member located between said ports, and separate levers nested one within the other and having a common fulcrum point for operating said valves.

3. In an engine of the class described, the combination with a cylinder having intake and exhaust ports in the head thereof,-

of inlet and exhaust valve boxes carried by said cylinder head and communicating} with said ports, said boxes having lever clearance recesses therein, inlet and ex-' haust valves for said ports and having dl secured their spindles exposed in said recesses of the inlet and exhaust valve boxes, a lever guide member located between said valves, 51'

spring'fastened in said member and connected with the spindles of said valves ndependent intake and exhaust valve levers nested one within the other and having a common fulcrum point, said levers workin in the lever clearance recesses of.the sai boxes to engage the valve spindles.

.In testimony whereof I have alfixed my signature in presence of two witnesses.
